Multiple Income Properties with a car deduction

Hello, 

I have multiple income properties and I want to add my car as a deduction on the totality of them.

 

Do I need to add the car under each properties (if so, do I divide the numbers by the number of properties) or if I add it under the first one the app will adjust the percentage amongst them ?

 

Thank you in advance !!

I would split the total expenses equally between the properties and claim on each property.
